Even though a particular installation scenario is supported, it might not be recommended.For example, you can’t install a 32-bit version of Visio on the same computer with a 64-bit version of Office. All installed products must be either the 32-bit version or the 64-bit version.See the example installation scenarios section for several examples of installation scenarios that are supported and not supported, along with an explanation of why they are or aren’t supported, based on the rules listed above.
What governs whether an installation scenario is supported are these two rules: The two main things that determine whether Office, Project, and Visio can be installed together on the same computer are the version of the product and the installation technology used to install the product. But, there are some combinations of Office, Project, and Visio that can't be installed together on the same computer. In many cases, you can install Office, Project, and Visio on the same computer.
